I cannot reproduce with the versions given below, and I think I recall lldb 360 being buggy in general, so I'm going to close this.

$ rust-lldb -v
lldb-370.0.42
  Swift-3.1
$ rustc -vV
rustc 1.19.0-nightly (cfb5debbc 2017-06-12)
binary: rustc

I'm getting the same issue with the following versions of rust/rust-lldb:

$ rust-lldb -v
lldb-370.0.42
  Swift-3.1
$ rustc -vV
rustc 1.19.0 (0ade33941 2017-07-17)
binary: rustc
commit-hash: 0ade339411587887bf01bcfa2e9ae4414c8900d4
commit-date: 2017-07-17
host: x86_64-apple-darwin
release: 1.19.0
LLVM version: 4.0

I've also tried using nightly and have the same problem.

Digging into this a bit more, it looks like it may be related to this issue: rust-lang/cargo#4056

When I run the debugger on the output file in ./target/debug/deps everything seems to work as expected

[jonas-schievink]

rust-lang/cargo#4056 has since been closed. Is this still an issue?

I've tried to reproduce this locally and I'm not able to. If someone can provide a reproducible example, the versions of everything involved, and the commands you've used then we can re-open this.

Tested using these versions:

$ rust-lldb -v
lldb-1500.0.17.10
Apple Swift version 5.9 (swiftlang-5.9.0.120.7 clang-1500.0.34.3)
